The new ARDX20 is based on the awesome tone of the old pedal, but adds several features that customers have been requesting, and are now needed in the ever-growing boutique delay market. About 100 pedals were sold in the summer of 2009, then full production ramped up, so availability should be good starting in September 2009. Designed by Analog Mike in the USA and primarily by Analog Man Japan, the pedal also has final assembly, calibration, and graphical engraving completed in Japan after being hand built to our precise specifications in China by a few assemblers who we chose for their excellent hand-soldering and detail work.
